You should show an interview example with engineering questions then. The questions in your example interview are technician-level. Checking a mechanical drawing for consistency is not an engineering task - the job that does that is "design checker". Design checkers typically have associate's degrees in drafting or CAD operation. The DFM question is arguably engineering but it could be even better answered by a machinist.

Engineering questions do not have to be complex, but they are different in kind.
